Good quality Hdi - The Mirror Aluminum Board | YMS PCB – Yongmingsheng

　　Aluminum plate is a metal base copper clad laminate with the following characteristics such as terrific thermal conductivity, machining property and gas-electric insulation performance.

　　Generally, there are three standands to gauge appropriately aluminum plate: Thermal conductivity, thermal resistance value and withstanding voltage.Therefore, when it comes to choosing the aluminute plate for the PCB where the above three standards is a major consideration.

　　Here are some parameters for your reference:

　　Board thickness:0.2-6.0 mm;

　　Copper foil thickness: 0.5–6.0 oz;

　　Thermal conductivity: 1.0–8.0;

　　Withstanding voltagel: 500V, 250V, etc.

　　Thermal resistance value:

　　Common aluminum plate: >1;

　　High thermal conductivity aluminum plate: <0.5 or <0.1 or less

　　In a nutshell, high thermal conductivity and low thermal resistance are the crucial factors when you are looking for suitable aluminum plate for the PCB.
